It is horrifying and also elucidating the main point, that sodomy is a worse sin than heterosexual rape -- since Abraham offers to at least not to step outside the boundaries of normal, heterosexual sexual appetite.
homosexual acts are central to the sins of Sodom
Indeed, other sins flow from this cardinal sin of sodomy. That is because a homosexual act is pure selfishness, -- there is no redeeming quality to it as there is no possibility of an offspring. No wonder the sodomites also turn out to suffer from "pride, excess or greed, and indifference to the poor and needy" -- they only think of their own pleasure.
